Abstract
An internal plug-in recuperator positioned within the exhaust assembly of a furnace for increasing the efficiency of a combustion furnace system by using less fuel input per heat output than conventional systems. Hot exhaust gases flowing within the exhaust assembly heat ambient air are directed through the recuperator before that air is injected into the burner. Preferably, the recuperator is constructed in a counterflow arrangement with an inner recuperator tube positioned within an outer recuperator tube.
